Choose an anchor one size larger and a drill bit the same size as the diameter of the screw of the cup hook you plan to use.
Drill a hole in the ceiling where you would like the cup hook installed.
Insert the anchor into the screw hole and lightly tap it into place with the hammer. If the anchor is slightly too large for the hole, make the hole a little larger with a slightly bigger drill bit. The size drill bit needed will depend on the type and material of the anchor.
Screw the cup hook into the anchor.
